The invention discloses a high-speed numerical control rotary working table which comprises a lathe body. A working table sliding base which can conduct rectilinear motion along the lathe body is installed on the lathe body. A working table body which can conduct rotary motion is installed on the working table sliding base. A working table static pressure system is adopted between the lathe body and the working table sliding base. The working table sliding base conducts the rectilinear motion on the lathe body. The working table body conducts the rotary motion on the working table sliding base. A static pressure guiding rail is adopted in the rectilinear motion. Static pressure unloading is adopted in the rotary motion. The frictional coefficient is small, load bearing is large, and the motion is smooth and steady. A measurement device of the rotary working table is a circular grating, and the indexing accuracy is high. A feeding shaft is in direct linkage through a servo motor, transmission intervals are eliminated, and high precision is achieved. The speed of the rectilinear motion of the sliding base is meters per minute, and the frequency of the rotary motion is a round per minute.
